..The results of this study suggest that polymorphisms in the CRHR 1 gene are not major risk factors for the development of alcohol dependence in persons of European ancestry...

Association of a polymorphism in the Homer1 gene with cocaine dependence in an African American population

John P DahlDepartment of Psychiatry, Center for Neurobiology and Behavior, University of Pennsylvania School of Medicine, Clinical Research Building, Philadelphia, 19104, USAPsychiatr Genet 15:277-83. 2005

..The purpose of this study is to determine whether single-nucleotide polymorphisms in the Homer1 and Homer2 genes associate with the cocaine-dependent phenotype in an African American population...

No association between polymorphisms in the prostate apoptosis factor-4 gene and cocaine dependence

Andrew E WellerCenter for Neurobiology and Behavior, Department of Psychiatry, University of Pennsylvania School of Medicine, Philadelphia, PA 19104, USAPsychiatr Genet 16:193-6. 2006

..The aim of this study is to investigate whether polymorphisms in the human Par-4 gene contribute to the etiology of cocaine dependence...

Analysis of variations in the tryptophan hydroxylase-2 (TPH2) gene in cocaine dependence

John P DahlCenter for Neurobiology and Behavior, Department of Psychiatry, University of Pennsylvania School of Medicine, USAAddict Biol 11:76-83. 2006

..This work suggests that variations in the TPH2 gene are not a risk factor for the development of cocaine dependence, but these findings require confirmation in larger, independent samples of cocaine-dependent and control subjects...

Variations in the vesicular monoamine transporter 1 gene (VMAT1/SLC18A1) are associated with bipolar i disorder

..Our results suggest that common variations in the CHRNA2 gene are unlikely to confer susceptibility to BPD in this sample. Further studies are required to elucidate the susceptibility locus for BPD on chromosome 8p21-22...

Analysis of variations in the NAPG gene on chromosome 18p11 in bipolar disorder

..The purpose of this study is to investigate whether polymorphisms in the human NAPG gene contribute to the etiology of bipolar disorder...

Lack of association between variations in the brain-derived neurotrophic factor (BDNF) gene and temporal lobe epilepsy

..Linkage disequilibrium was demonstrated throughout the gene. Results suggest that the polymorphisms we studied in the ATP1A2 gene do not represent major susceptibility factors for common forms of IGE...
